I'm still reaching here...

I was thinking of /proc.  Opening your own /proc/$$/* would certainly be
considered OK.  But, doing it for some other process not in your pid
namespace would not be OK and would not be checkpointable.

I know we're not quite in real-life territory here, yet, but I'm still
thinking.
